Hello: I've been wrestling with an integration issue for which there also seems to be one piece missing. I'm hoping someone on this list can help. Due to a complete lack of cooperation from our current voice provider we are in need of an alternative way to access our Octel 350 voicemail system from our SIP (SER) proxy. I can redirect and relay calls to numerous destinations via SER but because the Octel needs an SMDI interface for mailbox identification I am stuck, none of the solutions thus far support SMDI-SIP munging. I just started thinking about the possibility of using Asterisk with a few FXS cards to provide the gateway between SIP and the Octel. The problem is I still need an SMDI channel that is integrated with the message processing part of the gateway. Has anyone look worked or developed any working models that might help?
